Specification of Letters Patent.

Application filed September 5. 1905.

To all whom it moi, concern:

Be it known that l, JOHN H. KINEALY, a citizen of the United States,residing atFerguson, county of St. Louis, State of Missouri, haveinvented a new and useful Improvement in Air-Purifying apparatus, ofwhich the iOllOWillf is a lull, clear, and exact specification,rel'erenee being had to the accompanying drawings, which form a partthereof. .l y invention relates to that type of air Eurifying apparatusused in connection with eating, and ventilating systems wherein the airis freed of impurities by being Washed and then the moisture taken up bythe air during the Washing process is extracted by means ol' a Watereliminator.

The object of my invention is to makc the air supplied to buildings forventilating purposes clean. and sanitary by freeing it of his purities.And a further object of my invention is to )reveut damage to furnitureof schools and. other ventilated buildings by avoiding the introductionol dust and dirt. And a still further object of my invention is to coolthe air introduced for ventilating purposes in warm Weather so as tomake the airmside of the building cooler than the air outside. by an uparatus by moons of which the air is WlSllGll so as to free it of dirtand impurities and is then freed of entrained Water by means of 8. Watereliminator consisting of tubes formed and arranged as hereinafterdescribed and specifically claimed.

My invention is fully shown in the accompunying drawings Where similarletters are used to designate similar parts.

Figure 1 is a. sectional View of one form of the apparatus wherein theair passes horizontally througl'i the-Washer and the elimihater. Fir. 2is a rear View of the ehuunutor shown in Fig. i. Fig. 3 is a sectionalview of one form of the apparatus wherein the air passes horizontallythrough the wa her and Vertically throu 'h the eliminator. l'is 11 Viewlooking downwind on the eliminator shown in Fig. 35.

Referring; to the figures, A is a thoroughfare for the passage of theair; B is the washer; D, E, and F are sections of the tubes forming theeliminator; G is a center plate placed in the middle tube of oaohsection; and ii. are lips on the end 01 the tubes l'arthest from thewasher to prevent moisture being blown through. the tubes.

These several objects are attained Patented. Feb. tie, Serial No277.016.

The Washer shown in 1 consists of o. screen or veil oi Water a formed bymeans of the nozzles I) which are supplied through the pipe 0. Thewasher Fig. 3 gonsists or what 1 term 2. downward lallmg Water in a soor finely divided comiition. The irate ai -e to flow downward in dropsor stri-uuns, air in passing through this wall aigsags haul; and l'orthbetween the drops or streams of downward falling water coming inoontnet, however, with some of the water and it is not necessary to blowholethrough this Witll as. it is when a screen or veil of water such isshown. in Fig. l is used and, therefore, the air is likely to be morethoroughly Washed or i reed ol dirt than when a Veil is used. This Wallis formed by making the water pass from the bottom of a spray box cthrough a mun-- her of holes of. small diameter. supplied under pressureto the spray be}: through the pipef. in every case the veil r the walloi the w shor extends transversely across thc entire thoroughfare Air.

The operation oi the apparatus uni"? The air passing through the thorouenters the Washer ll Where it is washed by coming in content "with theveil of Water as shown in Fig. 1, or the whll of Water shown in Fig. 2.By the washer the air is freed oi dust and dirt, but has put into it agreater or less quantity of moisture in the iorm oi drops of water whichis carried forward with the air. After leaving the washer the sir entersthe elin'iinator Where it comes in contact with the surfaces of thetubes and. by rubbing on these surfaces it is made to deposit themoisture. The air rubs against the suri'uc of the outside of the tubesas Well as the sur' feces of the inside. lily melting the tubesconcentrieond larger at one end then the other so that the wells of thotubes are in clined to the axis of the eliminator, eddies are set upwhich malts it more ci'irte in that all the air 'will be brought inmintuctwith some parts of the tubes, and be made to de posit itsmoisture. By forming lips on the ends. of the tubes farthest irom'thewasher moisture deposited on the tubes is prevented from being blownthrough the eliminator. The center plate serves to prevent an. excessivoamount of air from passing through the center tube.

By using; fold water For the mupose of washing the air in Warm wvutluxrthe air l "l ater i e be cooled so that it may be at a lower tem eraturewhen leaving the apparatus-than w en entering it, and thus air suppliedto a building for ventilating pur os'es may be made cooler than the airoutsi e.

In. the drawings the tubes are shown arranged in three sections, but thenumber of sections and the number of tubes in a section ma be varied tosuit different conditions an the thoroughfare for the air may be of anysuitable material and itssizes and shape may be varied to suit eachparticular case, The tubes may be made of any suitable material andtheir size and shape may be varied to suit difierent conditions. Thethickness of the wall of water (i for washing the air and the amount ofwater flowing from the spray box e may be varied to suit therequirements of each particular case.

What I claim as new and desire to secure Letters Patent for, is:

1. In combination in an air purifying apparatus, a thoroughfare for theair, a washer, and a water eliminator consisting of tubes larger at oneend than the other, said tubes being provided each with a lip at the endfarthest from the washer and arranged in sections, and the tubes of eachsection being concentric, substantially asdescribed.

2. In combinationin an air purifying apparatus, a thoroughfare forthe-air, a washer, and a water eliminator consisting of tubes of theshape of a frustum of a cone, having each a lip at the end farthest fromthe washer and arranged in sections, and the tubes ofeach section beingconcentric, substantially as described.

3. In combination in an air purifying apaiatus, a thoroughfare for theair, means fbr forming a transverse wall of downward falling water in asprayed or finely divided condition, and a water eliminator consistingof tubes larger at one end than the other, said tubesbeing provided eachwith a lip at the end farthest from the wall of water and arranged insections, and the tubes of each section being concentric, substantiallyas described.

4: In combination in an air purifying aparatus, a thoroughfare for theair,-means or forming a transverse wall of downward falling water in asprayed or finely divided condition, and a water eliminator consistingof tubes of the shape of a frustum of a cone rovided each with a lip atthe end farthest rom the wall of water and arranged in sec-- tions andthe tubes of eachsection being concentric, substantially as described. 4

5. In combination in an air purifying apparatus, a thoroughfare for theair, means or forming a transverse wall of downward falling water in asprayed or finely divided condition, and a water eliminator consistingof tubes of the shape of a frustum ofa cone provided each with a lip'atthe end farthest from the wall of water and arranged in sections, thetubes. of each section being concentric, and the middle tube having acenter plate, substantially as described.

6. In combination in an air purifying apparatus, a thoroughfare for theair, a washer, and tubes larger at one end than the other,

, the tubes of each section being concentric and the middle tube havinga center plate, substantially as described. r

7. In-combination in an air purifying apparatus, a thoroughfare fortheair, a washer, and tubes larger at one end than the other arranged insections, the tubes of each section being concentric, and the middletube having scribed. In testiinony whereof I have signed my name to thisspecification in the presence of two subscribing witnesses.
